Wikipedia says:
The terms "integrated drive electronics" (IDE), "enhanced
IDE" and "EIDE" have come to be used interchangeably with
ATA (now Parallel ATA, or PATA).
This matches my understanding. Recall that IDE was essentially
ST-506 with all the analog bits done on the drive itself
(hence the name Integrated Drive Electronics).
